Description

A tall species, reaching up to 15 meters in height. Its horizontal branches end in rosettes of tapering leaves. This species can be distinguished by the white or brown spines on its leaves, and by its fruit-heads which hang on strongly recurved stalks. Each fruit-head has 100-150 5.6 cm drupes, which each protrude in a glossy green "pyramid". However, the exposed tip of each drupe is flattened (the areole) and - unlike '' Pandanus heterocarpus'' - without any corky margins. The basal joined portions of the drupes become light yellow when the fruit is ripe.Vaughan, R.E. and Wiehe, P.O. 1953. ''The genus Pandanus in the Mascarene Islands''. Botanical Journal of the Linnean Society 55:1-32.
